The frame A ot the improved machine is provided with legs or supporting members 7. and said frame is provided with cross bars 8 upon which longitudinally disposed track rails S) are supported. Suitably mounted tor longitudinal slidable movement upon the rails 9 is a base having a circular track '11 upon which the master wheel 12 is supported for rotation in an approximately horizontal plane, said master wheel being constructed with a gear wheel '13 engaged by a pinion l-l upon a shaft supported for rotation in a bearing 16 upon the slidable vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinailtm' fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred :lorm of the invention; it being, hmvcver. understood that no limitation is necessarily made to the precise structural details therein exhibited,

but that cl'iauges, alterations and moditica- 1 .Stlltl cross bar tions within the scope of the invention may be resorted. to when desired.

base 10 and having a hand wheel whereby it may be turned tor the purpose of rotating the master wheel.

The master wheel 19 is provided with upwardly exleiuliug lugs 18 serving to support a pair ol transversely disposed parallel. cross bars '19 which, by the lugs 18, are raised some distance above the level of the wheel proper. Said wheel is also provided adjacent to its edge with upwardly extending shoulders "20 and with lugs 21. supporting a cross bar the upper 'l'aces ot the Q2 and oi. the shoulder 20 being disposed in the same plane which is below the plane of the upper faces of the cross bars it).

The master wheel 12 serves to support the bed 2? ol the machine which consists of a circular disk or table providml upon its underside with transverse grooves 24: arranged in parallel relation and engaging the cross bars '15) of the master wheel. the shoulders 20 and cross bar 22 of which at tord supporting means for the under face of the bed which may be provided with 'llanges engaging said supporting means. It will be readily seen that the grooves 24; must be of sullicient depth to admit the cross bars 19. The bed or table 23 is surromnled by an annular 'lrame band 2:") provided upon its inner Face with a circiunferential rib 26 engaging a groove 27 in the edge oi. the bed or table which latter is capable of rotating within the band 95. while said band may be regarded as being supported by the rib 2(1 engaging the table.

The frame band is provided at diametrically opposite sides with upstanding brackets 28 supporting adjacent to their upper ends a rock shaft 29 having a handle 30 and an eccentric cam 31. The brackets 28 are connected together by a cross bar 32 which is provided intermediate its ends with a box-like casing 33, said cross bar being also connected by a longitudinally disposed bar 34 wit-h an upstanding bracket upon the frame band 25, the latter bracket being located about midway between the brackets 28 and adjacent to one end of the machine. The bar 32 is provided intermediate its central portion and the ends thereof with slots 36 wherein slides 37 carrying spring-supported centering pins 38 are adjustably mounted. The bar 34 is likewise provided with a longitudinal slot 39 wherein a slide 40 carrying a centering pin 41 is adjustable. The bars 32 and 34 are provided adjacent to the slots in said bars with suitable scales toward which pointers 42 upon the respective slides are directed for the purpose of exactly indicating the position of the centeri ing pins with relation to the axis of a shaft 43 which is supported for rotation in the bearing block 33, said shaft carrying at its lower end a presser plate or disk 44. The upper extremity of the shaft engages a cap 45 which is equipped with a ball bearing to enable the shaft to rotate without being subjected to undue friction. The upper extremity of the cap 45 lies in the path of the eccentric cam 31 upon the rock shaft 29, so that by turning said rock shaft, the cap 45 and the shaft 43 carrying the disk 44 will be forcibly moved in a downward direction. Means may be provided for automatically lifting the shaft 43 with its accessories, but such means are not absolutely necessary, and none have been shown.

The casing 33 is provided wit-h slots or apertures through which rack bars 33 are guided, the toothed faces of said rack bars being opposed to each other so that both will be engaged by a pinion 33 upon a short stem or shaft 33 which is supported for rotation in the casing 33, said stem being provided with a head or handle 33 whereby it may be readily rotated for the purpose of moving the rack bars 33 in opposite directions. Said rack bars are provided attheir outer ends with arms 33 lying in the path of and adapted to engage the pins 38 which may thus be simultaneously moved out-ward to any desired position. If desired, the arms 33 may be apertured for the passage of the pins which may then be moved either inwardly or outwardly with said arms and rack bars.

The brackets 28 afford bearings for a suitable eccentric rod 47 having a thumb piece 48, whereby it. may be actuated to depress the spring actuated centering pins 38. The frame of the machine is provided with a laterally extending bracket 49 which is slotted adjacentto its upper end for the passage of an arm 50 extending from the bracket 35 of the frame band 25, which latter is thereby held against rotation without interfering with the lateral movement of said frame band and the parts connected therewith when the base of the machine is moved longitudinally upon the supporting rails 9. Such longitudinal adjustment may be effected by means of an adjusting screw 51 operating in a bracket 52 which is supported upon the frame of the machine, the inner end of said adjusting screw being swiveled in a bearing 53 which is firmly connected with the base in any convenient manner. The longitudinally movable adjusting screw 51 is provided with a pivotally supported pointer 54 held against longitudinal movement by means of collars 55, said pointer being directed toward a scale upon an arm 56 which extends laterally from the frame.

A center of rotation for the bed or table 23 of the machine is provided by a bar 57 slidably engaging a diametrical groove 58 formed in the underside of the bed or table, where it intersects the parallel grooves 24, which latter are disposed equidistant-1y on the center or axis of the table, the groove 58 being obviously at right angles to the groove 24. The guide bar 57 is provided with a bracket 59 swiveled upon a block 60 in which latter is also swiveled the inner end of a horizontally disposed adjusting screw 61 which extends through a. threaded aperture in the base 10, said rod being provided at its outer end with a hand wheel 62, and said rod being also equipped with a pivotally supported pointer 63 arranged betw een collars 64, whereby it is held against longitudinal displacement upon the rod. The pointer is directed toward a scale upon the arm 56 in like manner as the pointer 54.

The frame of the machine supports adjacent to one end a supporting member 65 which is longitudinally adjustable by means of screws 66 and which has an upper inclined face upon which a bench 67 having a correspondingly inclined bottom face is adjustably mounted. The bench 67 is pro vided with bearings 68 wherein a shaft 69 is supported for rotation, said shaft being provided with means such as a pulley or band wheel 70 for receiving motion from the source of power, and said shaft carrying also a suitably constructed beveling cutter which is housed within a casing 71, it being understood that a cutter of any approved construction may be shown, as indicated in dotted lines at 72 in Fig. 1 of the drawings.

A bracket 73 rising from the frame band 25 carries a hingedly supported arm 74 equipped with. a handle 7 5, said arm being for the purpose of carrying an engraving tool 76 which may be of any suitable and approved construction.

In the operation of this machine the plate which is to be beveled is placed upon j the bed or table 23 where it is centered by i means of the centering pins 38 and 11, after which it is clamped securely upon the bed 1 by means of the presser plate 1st carried by the shaft 13 which is moved downwardly by the action of the eccentric cam 81. upon the rock shaft 29. \Vhile the plate is thus mounted in position, the table of the ma chine is moved outward upon the cutter by means of the adjusting screw 51, whereby the base carrying the master wheel and the table is moved longitudinally of the fran'ie. After the plate has been centered and secured upon the table, the latter is restored to a position where the edge of the plate will be engaged by the beveling cutter, the latter being adjustable with reference to the work by moving the bench c7, and the centering bar or slide 57 is now adjusted by means of the screw 61; it being, of course, understood that absolutely perfect adjustmentmay be made owing to the presence of the pointers 54L and (f?) directed toward the scales upon the arm 56. The master wheel is now rotated by means of the hand wheel 17. thus causing the bed or table to rotate in a horizontal plane, the axis of rotation being. however, gradually shifted as the work progresses, owing to the trammel construction of the underside of the bed or table .23 which is movable in two directions guided by the cross bars 19 and the slide 57, which latter by making the groove 58 in the underside of the table sufficiently shallow, will be cleared by the correspondingly elevated cross bars 19 as the operation progresses. The entire circumference of the elliptical or oval plate will thus be gradually presented to the beveling cutter, whereby the edge is beveled, as will be readily understood. After the completion of the beveling operation, the engraving tool carried by the pivotally supported arm 74: may be brought into requisition for the purpose of forming concentric elliptical lines upon the face of the oval plate.

It may be considered advisable especially for certain classes of work to move the en tire bed of the machine including the supporting rails 9 longitudinally with reference to the beveling cutter which is sup orted upon the bench 67. To enable such adjustment to be conveniently effected T provide the modification illustrated in Figs. 8. 9 and 10 under-which an additional set of rails, here designated by 90, are interposed between the rails 9 and the supporting frame, said rails 90 being in this instance supported upon the cross bars 8 of the frame. while the rails 9 are connected together by cross bars 91, as shown in dotted lines in Fig. 9. The frame is provided adjacent; to the end of one of the rails 90 with an arm or bracket 92 affording the bearing for an adjusting screw 93 which operates in a box 9 1; connected with the structure including the rails 9, said box being equipped with a pointer 95 directed to a scale 96 upon the arm or ln'acltet 92. A hand wheel 97 is provided for convenient manipulation of the adjusting screw. l t will be seen that by this simple arrangement the rails 9 and the entire supcrstructin'e connected therewith is capable of longitudinal adjustment upon the frame and that the extent of such adjustment may be readily determined. \Vhen this modification is resorted to, it is preferred also to remodel the bench (37 which supports the bevcling tool and the support ing means therefor. Under the construct ion illustrated in Figs. 1 and 2, the bench is provided with an inclined bottom engaging a correspondingly inclined top face of a supporting member (35. Under the present modification the bench. here designated 9b. is equipped with supporting flanges 99 and 1.00, the former of which has an inclined bearing face, while the latter has a straight face, as clearly seen in Fig. 10, said flange being hingedly connected with a supporting flange 101 rising from the table. Secured adjustably upon the table is a supporting member 102 having an inclined upper face corresponding with the inclined face of the flange 99, said supporting member being adjustable by means of a set screw 19?). Bolts 10st: are also provided, said bolts extending through slots 105 in the adjustable supporting member 102 and i'ipwardly through the top of the bench 98 where tightening nuts 106 are provided. it will be seen that by loosening the nuts 106 the supporting member 102 may be readily adjusted to raise or lower one end of the bench. thus effecting a very n'iinute adjustment of the beveling tool carried by the bench. After the proper adjustment has been effected. the parts may be secured very firmly by tightening the nuts 106.

In the operation of the machine constructed with the modifications just described. the width and length of the o al are first determined by the pointers (i3, 54; the plate is clamped under the presscl' head. and now the adjusting screw 93 is turned by the hand wheel 97 to move the entire bed of the machine including the rails 9 and the parts supported thereon to the proper position with reference to the bercling tool. It is preferred that a lug or stop be attached to the scale so that the bed of the machine will not move beyond the desired prcdetcrmincd point, and the master wheel now put in rotation. The bed is now taken from the cutter head, and the engraving tool is let down, and the master wheel is again putin rotation aml as many lines as may be desired may now be engraved. and the plate is then removed. It. will thus be seen that owing to the presence of the auXiliary track the entire movable base of the machine may be moved to or from the relatively stationary bench carrying the bevel tool without resetting or changing the size.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skill-ed in the art to which it appertains.
